my inbox on Dec. 4, '25 completely disappeared -- not located in other folders, how to retrieve

If your emails have disappeared from your Inbox in Outlook, there are a few steps you can take to try to recover them:

1. Check Other Folders: Sometimes emails can be accidentally moved to other folders. Check your Deleted Items, Archive, or any custom folders you may have created.
2. Use Advanced Find: You can use the Advanced Find feature to search for your emails. Here’s how to do it in Outlook 2010 and later versions:
   • Select the Inbox folder.
   • Click into the Instant Search bar to display the Search tab.
   • Select Search Tools, then choose Advanced Find.
   • In the Look for list, select Any type of Outlook item.
   • Select Browse and choose the root folder (your email address), ensuring Search subfolders is disabled.
   • Click Find Now to see if any messages appear.
3. Check Filters: Sometimes, items may not be visible due to applied filters. To check this:
   • Go to the View tab in the ribbon.
   • In the Current View area, select View Settings.
   • Click on Filter and review the settings to ensure nothing is filtering out your emails.
4. Resync Your Account: Since you mentioned trying to resync, ensure that your account settings are correct and that Outlook is connected to the internet. You can also try removing and re-adding your email account in Outlook.
5. Contact Support: If none of the above steps work, consider reaching out to Microsoft Support for further assistance. They may be able to help you recover lost emails or troubleshoot the issue further.

Hello,

Since it was a migration from old outlook to new outlook the folder setup might not have migrated properly, try opening classic outlook again.

Hope this helps,
